Maria Sharapova, the epitome of grace and elegance on and off the court, has kept her private life rather private over the years, including her romance and subsequent engagement to former Laker Sasha Vujacic.

Since the former No. 1 women's tennis player in the world called off the wedding plans last year with Vujacic, there had been plenty of speculation as to budding romances. That has come to an end.

During the Madrid Open this week, Sharapova was photographed hand in hand and lip to lip with Bulgarian tennis star Grigor Dimitrov.
